Restrict Access by Gateway/Service using source ip

[rlljorge]

@Shubham

you can try with namespace in which your gateway is like default. AFAIK namespace: istio-system
apply the policy to all gateway (which reference to istio-ingressgateway) in the mesh.

@Shubham I tried this away in previous test

...
metadata:
 name: deny-all
 namespace: istio-system
spec:
 selector:
   matchLabels:
     app: istio-ingressgateway
 action: DENY 
...

I did not succeed …
